SPINDLE-LUBRICATOR.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed March 18. 1907. Serial No. 363,076.

T 0 all whom it may concern;

Be it known that I, \VILLIAM FIELDING, a citizen of the United States,residing at Lewiston, in the county of Androscoggin and State ofMaine,have invented a new and useful Spindle-Lubricator, of which thefollowing is a specification. 7

This invention relates to bearings and lubricating devices for thespindles of spinning frames and the like, and has for its principalobject to provide a novel form of bearing having a lubricant reservoircommon to a series of spindles, the reservoir and the bear ing being soconstructed that frequent lubrication will not be necessary.

A further object of the invention is to provide a bearing and lubricantreservoir of such construction that the lubricant will be automaticallydistributed from the reservoir to a large number of spindles, and whichwill prevent loss of lubricant and the accumulation of dirt and dust inthe lubricant reservoir or around or adjacent to the spindle.

A still further object of the invention is to provide an improvedbearing from which broken or bent spindles may be readily re- I moved.

lVith these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features ofconstruction'and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform, proportions, size and minor details of the structure may be madewithout de arting from the spirit or sacrificing any 0' the advantagesof the invention.'

In the accompanying drawings :Figure 1 is a transverse sectional view ofa spindle bearing constructed in accordance with the invention. Fig. 2is a sectional plan view of a portion of the same. Fig. 3 is a detailperspective view of one section of the hearing. Fig. 4 is a similar viewof the opposite section of the bearing.

, Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The carriage 1 is generally formed of H011 or steel and to this carriageis secured a collar board 10 formed of brass or other suitable material,the collar board being provided with a number of notches 11 generallyten in number for the reception of ten spindles, the bearings which formthe subject of the present lnventlon being each designed to hold aseries of ten, more or less, spindles.

Projecting from the forward face of the collar board is a rib 12 that[its within a groove 13 formed in the outer section 1.4 of the brasscollar board, this groove 13 constituting a lubricant reservoir to whichlubricant is supplied through an opening 15, the lubricant beingpreferably in the form of melted tallow or similar material, which willsolidify when cooled. The opening 15 is provided with a threaded closingplug 16 which is placed in position after the reservoir is filled inorder to prevent the entrance of dust and dirt. The ends of thereservoir are formed by suitable lugs 18 that project from the end.portions of the rib 12 in order to prevent the escape of the lubricant.

The inner face of the outer section 14 of the collar board is providedwith notches 20 of a number corresponding to the number of notches 11,and these notches are made in pairs that constitute bearings for thespindles. The two sections of the collar board are held in properrelative position by securing screws 21 or similar members which maybetightened for the purpose of taking up wear on the hearings orspindles, as may be necessary from time to time.

It will be observed that all of the bearing notches 11 open directlyinto the lubricant reservoir, so that one side of the bearing is inconstant communication with the reservoir, and the lubricant may havefree access to the spindle, and in order that the lubricant may bebetter distributed, the outer face of the rib 12 is provided withobliquely disposedgrooves 25 which serve to some extent to direct thelubricant in the direction of the spindles.

The wearing side of the collar board or spindle is that side nearest thecarriage 1, owing to the natural pull of the b ands on the spindlewhirls. In order to keep this side of the spindle thoroughly lubricated,the upper edge of the portion 10 is provided with a collecting groove 24for the grease, and the outer portion of the collar board has aninclined top in order that any grease which may collect may run bygravity down to the groove.

The construction is such that all wear may be readily taken up, and incase of a broken or bent spindle the outer section of the collar boardmay be readily removed in order that l bearings, one section of thecollar board havthe spindle may be replaced.

I claim 1. In a device of the class specified, a tWo part collar boardhaving spindle bearing recesses, the sections of the collar board havinginterfitting ribbed and grooved portions constituting a lubricantreservoir.

2. In a device of the class specified, a two part collar board notchedto form spindle bearings, one section of the collar board having agroove constituting a lubricant reservoir, and the other section havinga rib that fits partly Within said groove.

3. Ina device of the class specified, a two part collar board notched toform'spindle bearin s, one of the sections of the collar board eingprovided With a projecting rib, the outer face of which has inclinedrecesses, the opposite section of the collar board having a ribreceiving groove that constitutes a lubricant reservoir.

4. In a device of the class specified, a two part collar board notchedto form spindle ing a projecting rib, the outer face of which hasobliquely disposed grooves, the opposite section of the collar boardhaving a rib receiving groove constituting a lubricant reservoir, lugsprojecting from the face of the rib and closing the ends of the groove,and. means for adjusting the sections relatively to each other to takeup Wear.

5. In a device of the class specified, a tWo I part collar board, theupper face of one of the collar board members being provided With alongitudinal groove, and the other member being inclined in thedirection of such groove, substantially as and for the purposespecified.

In testimony thatI claim the foregoing as my own, I have hereto affixedmy signature in the presence of tWo Witnesses.

WILLIAM FIELDING.
